Ground penetrating radar ultra wide band antenna

The invention discloses a ground penetrating radar ultra-wideband antenna, which comprises an antenna dielectric plate and two microstrip patches, and is characterized in that the antenna dielectric plate is a horizontally arranged rectangular plate body, and the long edge of the antenna dielectric plate is in the left-right direction; the two micro-strip patches are incomplete wafers with the radius r, one end of each micro-strip patch is a complete semicircle, the other end of each micro-strip patch is a notch end, and the notch ends are feed ends; the notch end is in a circular arc shape protruding towards the side away from the circle center, and the curvature of the circular arc is smaller than an arc line at the complete wafer formed by the incomplete wafer. The two microstrip patches are stacked on the upper wall surface of the antenna dielectric plate and are arranged left and right, the complete semicircular ends are located at the left end and the right end of the antenna dielectric plate, the notch
